LATE-CUTTING MACHINE.

Specification of Letters Patent No. 4,787, dated October 3, 1846.

To all whom it may concern Be it known that I, JAMES M. WINSLOW, ofCampbells Port, Portage county, State of Ohio, have invented a new anduseful Machine for Cutting Laths, which 1s de-. scribed as follows,reference being had to the annexed drawings of the same making part ofthis specificatiton.

Figure l is a side elevation of the machine. .Fig. 2 is a frontelevation of machine. Fig. 3 is a vertical longitudinal section. Fig. 4is a top view. Fig. 5 is a sectional view showing the pointed mandrel,pinion and screw.

v The machine in its improved form consists of the following partsnamely: A substantial wooden frame a a b b 0 0 d d e e) of which theuprights a a contain a cast iron slide A A; in which slide there areplaced the boxes B B of the gudgeons B B of the pinions C C, which fitinto the mandrels D D, which mandrels have on their inner face points Dto afiord them a hold on the log; there is a screw E E journaled intothe outside of each gudgeon B B which works inside the center of thepinion l1aving a shoulder pressing against the end of the pinion and byturning the winch F F attached to the head of the screws the points ofthe mandrels are forced into or drawn out of the log. The pinions c 0gear into an eccentric rack G G which is so formed that every motion ofthe pinions the distance of one log removes it one inch and a quarter(the width of the lath) farther from the center of the said eccentricrack thus keeping the upper side of the log at one uniform height. Theupper knife is formed of a steel plate It attached to a cast iron plate6 Fig. 3 by set screws. The outer edge of the steel plate is of coursemade sharp. The perpendicular. knife 7 is made to cutinto the log oneinch and a quarter at every stroke by means of the cranks L L whichconnect by the miter wheels M M with the shaft on which is the fly wheelN and the pulley 0 when the power is applied. One of the crank shaftsterminates in a small crank P Fig. 4: which through the medium of theconnecting rod Q, which rod works in a ball joint at R and imparts inconcert with the arms S S Figs. 3 and 4 a vibrating motion to thehorizontal knife 7c which is made thereby to cut the thickness of a lathinto the log. This horizontal knife is secured to a sliding plate m byset screws around the ratchet wheel and its attached roller Vsufliciently far to turn the log the thickness of a lath by means of thepoints "0 on the surface of the roller.

The foregoing parts of the machine are not claimed. That which I claimis the following and relates, 1st, to the arrangement of the bearings ofthe feed roller. 2d, the manner of sustaining the knives by a newarrangement of set screws, and 3d the peculiar arrangement of arevolving notched counter, all of which are described as follows.

The bearing plates H before named are made of metal of a rectangularform and are perforated with oblong slots i or mortises Fig. 1 toreceive the gudgeons of the feed roller V and also with round a tures toadmit screws or bolts by which they are fastened to the posts. Theoblong mortises z aforesaid are made of sufficient size to allow thegudgeons of the feed roller to rise and fall freely.

In order to make the knife that makes the vertical cut steady in itsmovement I cause the knife stock 1 to move obliquely between the ends orpoints of screws L passed through the two upper horizontal. parallelcentral timbers of the frame and in contact therewith. As the points ofthe screws wear they are screwed up against the stock by simply turningthem.

The screws w for steadying and adjusting the stock 'm, of the horizontalknife are passed up vertically through the cross timber 10 of the framehaving their points against the under side of the knife stock.

The revolving notched wheel A for keeping count of the number of lathscut is placed in a vertical position on a horizontal pin A inserted intothe side of one of the horizontal top pieces of the frame aforesaidmarked on the face 100, 1000 or any number according to the number ofnotches in the periphery of the wheel .in which notches there is made tolie a hand A which is attached to an arm Q connected to the wrist of oneof the crank shafts P and the horizontal knife so that at every sweep ofthe knife the said hand is made to act against one of the teeth of thewheel and to turn the wheel the distance of a tooth at each cut of thehorizontal knife. A pointer C Fig. 4, is fastened to the top of theframe in a horizontal position to indicate when the wheel has performeda revolution.

Operation: First fix the mandrel D firmly into the center of each end ofthe log Z then raise it to its place on the eccentric racks G G andhaving inserted the pinions fix the whole firmly in their place by meansof the screws E then apply the strap to the pulley O and the machinewill after a few cuts commence turning out good laths which it must beallowed to do until the log is re- JAMES M.
